摘要
在海底管道进行海上油气资源输送或停输过程中，原油（气）受较低海洋温度影响，容易形成蜡等水合物阻塞管道，给安全生产造成很大隐患，因此，通常情况下都需要对海底管道进行有效保温，确保管线安全运行。本文主要介绍了国内外海底管道常用的保温结构及其应用特点。
Crude oil or gas will form wax and hydrates to block the pipe because of low temperature during the subsea pipes are operated or shut off. This will do harm to production safety. So effective ther- mal insulation is needed for subsea pipeline to ensure safely running. The thermal insulation structure and specialities for foreign and domestic subsea pipeline . are introduced.
